Age, gender, visual performance and cognitive ability are associated with the size and shape of the asymmetric attentional visual field, which encompasses central and peripheral visual fields.

WAILEA, Hawaii — Posterior pole buckling can reduce the progression of high axial myopia, a physician said here.

There may be a common genetic thread that links axial length and myopia, according to a large study by researchers in Australia.

A study using data from the World Health Organization's Vision 2020 initiative has identified a relatively small yet significant prevalence of undiagnosed refractive errors among working-age adults in Britain. In addition, the study found that these people may be adapting daily activity to accommodate these visual deficiencies.

Myopia prevalence is higher among Danish patients with diabetes than in the normal population, suggesting that poor metabolic control of glucose may be a risk factor for myopia, according to a study.

A study has estimated that clinically relevant refractive errors affect half of the people in the United States aged 20 years or older.

Peripheral prism glasses can improve general mobility in patients with hemianopia, according to a multicenter study published in the May issue of Archives of Ophthalmology.

The first topic that is gaining attention in optics is that of pinhole optics. We have discussed the AcuFocus ACI 7000 corneal inlay before. The trial for that is on hold in the United States right now because the developer wants to fine-tune the optics, including the thickness and number of holes, so that when they complete phase 3, they will have exactly the inlay that they want.

Optical eccentric refractive correction may improve the resolution acuity of patients who have central visual field loss, according to a small study.

Using spectacles to correct the refractive errors of nursing home residents improves their quality of life and reduces symptoms of depression, according to a study by researchers in Alabama.
